Boeing 787 Dreamliner is supposed to be one of the best planes in terms of its design, fuel efficiency and advancement of the technology. Everyone understands that every plane requires battery for backups or some electrical applications. However, the Dreamliner uses the Li-ion battery based on Lithium cobalt oxide (LiCoO2) extensively. It is because it is designed in such a way to use electrical signals for control system unlike the earlier planes with hydraulic control system. All 787s have two Li-ion batteries weighting around 63 pounds, compared with 106 pounds for nickel-cadmium battery in 777s, and holds electric charge of 65 ampere-hours, compared with 47 ampere-hours for 777 battery and measures 8.6 inches tall by 11 inches wide in dimensions... Overheating and catching fire by Li-ion battery in laptop, smartphones and electric vehicles has already been reported in many instances. However, such issues were not reported in aircraft because the Li-ion battery was not used for the electrical system in the planes to the extent as in Dreamliner.Read more here...
